Reddit reviews HOMREE DC-DC Converter Step Down Module 12V to 5V Micro USB Output Buck Power Adapter

I would suggest upgrading the chassis fan too 10$ and you have a better quieter fan. Also a note about the power supply, there isn't much room in there, you may need to extend the base up with wood or some sort of printed base. I saw this in a tutorial once, don't remember where.

I heard some people had gotten broken fillament tensioners after a while. You can consider upgrading the extruder drive. I ordered this one on amazon and it fit perfectly on my v2. I never got to try flexible filament but I have a hunch it can do it since the drive gear is very close to inlet guide.

Lastly to make your life easier with Octoprint for Raspberry Pi, I tested it and it was fantastic. No need for using SD cards anymore or leaving your computer on, and you can monitor the print remotely with a webcam. After a while I put my PI in the printer chassis I wanted it to be as clean as possible. This will require a nice side panel with a USB port, and I’d recommend a pi switch to safely turn it off but you can use the print interface for that. You probably will need a 12v to 5v stepdown converter. I used this one since it connects directly with the Pi, and had no problems with it. To run this extra electronics and a LED light strip on mine I got a generic 150w PSU just for peace of mind.

Edit: Here is the imgur Gallery with my Fan mods and my Pi mod and LED strip. Also you will need to adjust your extrusion steps if you upgrade the extruder drive, links below.

I am running one using this converter on a 12v system. It has the micro usb to plug directly into the pi.

Edit for more info

I am using a solar charge controller from Victron.

You could also get one of the cheap Renogy charge controllers that have USB output. Search for renolgy wanderer on amazon. I am not sure this one has temperature compensation so it may be hard on your batteries.

That's a passive PoE injector, meaning plugging into a powered PoE switch will not work. It is a 2-piece system that just uses a DC power supply at the source end, feeds power over the unused conductors, then separates it back out at the other side, and it also doesn't have the greatest range at 50ft or so max.

If you're going to use with 802.3af PoE switch, then you want this one, which will actually take power from the PoE switch and won't need a separate power supply.

Additionally, if you've got a 12V DC power supply in the old alarm box or can install one, you can use these buck converters which will drop 12VDC to 5V3A micro USB, which will power the keypads just fine.

Yeah I realized I'd need something to change the voltage, then found this thing : https://www.amazon.com/dp/B01MEESLZ6/ref=cm_sw_r_cp_awdb_t1_IiL0Cb37AN4WE

I think with the one you linked I'd need another separate USB cord to connect to the cam, this one I can plug right into it.

I'll probably go with the t taps since I've used them before, my last question is, I can attach the t taps then test the taps with the multimeter, right?

Pi works fine with regular adapter. It states in the product details:

Input voltage: DC8-20V, (12V changes to 5V)

• Output parameter: DC5V3A, 15W
  
• Size: 46x27x14mm
  
  Ordered this one

Do you already have an existing hardwired keypad with wires? If so, I used an adapter on one end (my wires terminate in my basement) like this one . I used a MicroUSB converter on the keypad end. You might need to make the existing hole larger. I used something like this.
